摘　　要：采用快速溶剂萃取技术提取油砂沥青,通过单因素试验和正交试验得出加压溶剂萃取技术的最佳工艺参数。研究结果表明,在高压条件下,混合适量硅藻土分散剂,快速溶剂萃取法提取油砂沥青比传统索氏抽提与费舍尔试验更有优势。利用正交试验获得快速溶剂萃取法提取油砂沥青的最佳工艺参数为:压力10 MPa,土砂比(硅藻土与油砂的体积比)2∶1,萃取温度160℃,循环次数5次,溶剂选择四氢呋喃,单次静态萃取时间12 min。Accelerated solvent extraction technology was used to extract oil sands bitumen,and the optimum technological parameters of pressurized solvent extraction technology were obtained by single factor test and orthogonal test.The results show that the accelerated solvent extraction method is superior to the traditional Soxhlet extraction and Fisher test in the pressure condition and the mixture of diatomite dispersant.The optimal process parameters of accelerated solvent extraction for the extraction of oil sands bitumen were obtained by orthogonal test as follows:a pressure of 10 MPa,a soil-sand volume ratio of 2∶1,an extraction temperature of 160℃,a times of cycles of 5,solvent tetrahydrofuran,and a single static extraction time of 12 min.
